A kind of preparation method of the γ-MnOOH nano wire of the morphology controllable for phenolic wastewater treatment, it is related to a kind of material for water treatment preparation method, the method includes following preparation process: surfactant is dissolved in high purity water, add potassium permanganate, to being completely dissolved, acquired solution is reacted under high temperature and high pressure environment；By gained catalyst detergent, centrifugation and drying to obtain γ-MnOOH nano-wire catalyst；The draw ratio of nano wire can be by adjusting preparation parameter control in 12-20；The mass ratio of potassium permanganate and surfactant is 6:4-9:7；Preparation process is using ethylene glycol, cetyl trimethylammonium bromide, neopelex as surfactant；The bushing of hydrothermal synthesis reaction kettle is polytetrafluoro material；This method is easy to operate, and yield is high, and reaction process is environmentally protective.In the case where the ratio between amount of persulfate oxidation agent and phenolic comp ' ds pollution substance is less than 5, removal rate reaches 99.9%. |
